  56  * Description:
  57  *  Structure holding timing and resolution information of a standard.
  58  * Used by vpbe_device to set required non-standard timing in the
  59  * venc when lcd controller output is connected to a external encoder.
  60  * A table of timings is maintained in vpbe device to set this in
  61  * venc when external encoder is connected to lcd controller output.
  62  * Encoder may provide a g_dv_timings() API to override these values
  63  * as needed.
  64  *
  65  *  Notes
  66  *  ------
  67  *  if_type should be used only by encoder manager and encoder.
  68  *  flags usage
  69  *     b0 (LSB) - hsync polarity, 0 - negative, 1 - positive
  70  *     b1       - vsync polarity, 0 - negative, 1 - positive
  71  *     b2       - field id polarity, 0 - negative, 1  - positive
